Distillation made heuristic. Nothing explains a process like a little hands-on experience, and this laboratory distillation kit is for showing instead of telling. Includes a 300mm Liebig condenser, Kjeldahl distilling column with 50mm dia bulb and rubber stoppers, 500ml Bomex boiling flask with 8" iron tripod, 2-foot lab stand/base with a single burette clamp, 500ml graduated Erlenmeyer flask and a 6" square of ceramic-coated wire gauze. You add some 1/4" ID tubing for the Liebig ports. Includes good directions for distilling ethanol and acetic acid. And let's remember that this is for laboratory distilling. Don't try this at home.
A great find: sterile plastic petri dishes, 100mm dia x 15mm deep, with a loose fitting lid. Great for growing cultures for your science fair experiments. Our each (20) dishes and lids in a sealed, sterile package.
Chemically treated paper strips to test for acid or base (alkaline)
solutions. Use the blue for acids, the red for bases. The more
sophisticated pH test paper strip indicates pH from 1 (bright red) to 14
(dark brown). Values in between can be read by comparing with a color
chart that comes with the strips. All have (100) strips of test paper
Rejoice, we have finally found a source of reasonably priced
borosilicate lab glassware. This is the kind of glass in the trade
marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over
the flame of the Bunsen burner, or directly onto the hot plate. This
stuff is imported from China, and is considered student grade, which is
good enough for anything but the most exotic applications. We have
beakers, test tubes, graduated cylinders and flasks. Compare the prices
below and you will see that they are around half the U.S. equivalent.
Call us for larger quantity prices.
Here’s a fine pair of nylon bristle brushes, just perfect for cleaning
test tubes, aquarium filter tubes or your favorite long-necked soda
bottle. The smaller brush is 8-1/2” long with a 1/2" dia. while the
larger is 10-1/2” overall with a 1-3/8” dia. The bristle area for both
is approx. 3-1/2” long.
Porcelain mortars and pestles. Great heavy duty mortars, with sides that
are easily 5/16" thick on the smaller ones, and up to 1/2" on the
larger. The mortars are glazed outside, but rough inside, the better to
grind, and have a pouring lip. The business ends of the pestles are
unglazed, while the shafts are glazed. Very functional, very good
looking!! So grind your own spices or lab concoctions as you prefer.
You get a mortar and pestle as a single order.
Inside the lab, it's a standard translucent-white, LDPE-plastic wash bottle, 500ml/16oz, measuring 2-3/4" dia x 6-3/4 tall with a screwcap and a right-angle, 5/16" dia nozzle. Outside the lab, it's so pleasing to squeeze and squirt with that some of us keep them in the kitchen.
Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.
This pocket microscope measures just 1-1/2" square x 3/4" thick but magnifies 50X. Don't inspect jewelry without it. The mighty mite comes with (3) button cell batteries to power a pushbutton UV and a slide-switch for (2) bright-white LEDs, (1) aimed straight down and (1) aimed at an angle to the subject. Has a focus knob and a small wrist strap and carrying pouch.
